Guild Wars 2

Not sure if this has been asked or answered before.
I got my first skin by exchanging 50 Bauble Baubles with Moto, it says its account bound.
But i still see skins listed on the TP.
Was wondering where those are coming from.
from what i read on Wiki skins from Moto or the chest are account bound.
Plz help solve my mystry….

There is a 1 in 50 chance to get a dropped skin from the chests at the end of each zone. These skins are sellable on the TP. The skins from Moto are account bound.

Non account-bound skins drop very rarely from the boss chests(ie: the ones in the cages and from the frog) in SAB.

i thought so.
thx for confirming
